SSBC proportioning valve questions

While doing my brake kit i also decided to get new stainless steel brake lines.
Removed them the other night, but i also looked to see where the proportioning valve would mount. It doesn't appear to be much room behind the distribution block for the valve with the included 2 inch long line. Where have you mounted them?

Also, with stainless steel lines, can i cut them and double flare them? or is stainless too hard?

Thanks
